There seems to be a bug where Namazu Trader re-entering the battlefield is not triggering its enter effect:
1. Opponenet's Namazu Trader was exiled under my white auracite
2. Suplex exiles white auracite
3. Namazu Trader re-enters the battlefield back on opponent's side
4. no enter triggers - note opponent is at 1 life.

Namazu Trader's effect isn't a cost and it isn't optional - the effect should have triggered when Namazu Trader re-enters the battlefield on my opponent's side and should make my opponent lose 1 life therefore losing the game. But this didn't happen and I lost the game because of it.

Very annoyed to say the least as this was in Premier Draft.
